 Posted: Mon Aug 21, 2006 2:06 am Post subject: Kernel 2.6.17-r4 w/ genkernel not forwarding traffic. |
 |
|
I recently did a 'emerge -vp world' to see if there was anything that needed updating on my system. It was showing a new kernel was available.
2.6.17-r4. So I emerged it and since I used genkernel on my previous kernel (on install of the server) I figured I would let this one go as well. I did notice that there was a new genkernel to be emerged as well so I emerged that before hand.
I issued the 'genkernel all' and went to watch TV. 
When I came back I modified my grub.conf to load the new kernel and rebooted. All seemed fine. All my services were up and happy.
I come into work today and SSH into my server. I have Putty setup to TCP forward some services via the SSH tunnel for things like MS RDP to my MS servers and VNC to others. However none of the forwards were working. I checked my sshd_config and it looked fine. After about an hour of messing around I figured I would load the older kernel and see what happens.
So I rebooted and setup the server to load its original kernel (2.6.16-r13) again made with genkernel as well. After the reboot, all my TCP forwards worked without an issue.
Can someone please enlighten me as to what I'm missing with the new kernel? I'm not exaclty sure what I'm doing wrong.
When I look in the System map file for each in /boot this is what I found for forwarding. Which both appear to be the same.

Just to add to this. I get the same issue with 2.6.17-r7. Again made with Genkernel. I can't believe I'm the only one who has this issue.
thanks |
